html

js，要引入layui.js

layui.use('flow', function() {
        var $ = layui.jquery;
        var flow = layui.flow;
            flow.load({
            elem: '#container' //流加载容器
               //滚动条所在元素，一般不用填，此处只是演示需要。
            ,done: function(page, next){ //执行下一页的回调
              console.log(page)
              //模拟数据插入
              setTimeout(function(){
                var lis = [];
                var url = "/index/index/ajaxNews/?page="+page
                $.get(url,function (res) {
                    
                        layui.each(res.msg.data, function(index, item) {
                            lis.push('<div class="layui-row list">\
                                <a href="newsDesc/id/'+item.id+'">\
                                    <div class="layui-col-xs4 layui-col-sm4 ">\
                                        <img src="'+item.cover_img+'">\
                                    </div>\
                                    <div class="layui-col-xs7 layui-col-sm7 right">\
                                        <div class="title">'+item.title+'</div>\
                                        <div class="intro">'+item.intro+'</div>\
                                    </div>\
                                </a>\
                            </div>\
                            <hr/> ');
                        });//组装html
                        //pages为Ajax返回的总页数，只有当前页小于总页数的情况下，才会继续出现加载更多
                        next(lis.join(''), page <= res.msg.pages);
                    
                })
              }, 300);
            }
          });
    });
    </script>

php Controller控制器

public function ajaxNews()
        {
            $page = input('page');   //页码
           $pagesize = 6;
           $list['data'] = model('Index')->getNewsList($page,$pagesize);
           $count= model('Index')->getNewsCount();
           $list['pages'] = ceil($count/$pagesize);
         return $list;
    
        }

php model模型

// 获取动态列表
        public function getNewsList($page,$pagesize)
        {
            $list = Db::name('news')
                ->field('id,title,intro,cover_img')
                ->order('create_time desc')
                ->where(['status'=>0])
                ->page($page,$pagesize)
                ->select();
            return $list;
        }
    
        //获取动态总条数
        public function getNewsCount()
        {
            $count = Db::name('news')->where(['status'=>0])->count();
            return $count;
        }
